Downhauling an NP RX2

Downhauling an NP RX2

Post by windsofa » Sun, 20 Aug 2000 15:01:27


Learning to tune my RX2 8.4 (luff is 508 +/- 1). . . or failing. I have a
Chinook double-bolt 45 cm (aluminum) and the RacePro 490. The trim guide for
the RX2 is no help at all in trying to figure this out (thanks for the
multimedia CD NP, but I'd go for more tech stuff any day). So I went back to
the RX1 trim guide and used their guidelines. Is this my first mistake?

When I set the Chinook to 20 cm, it measures 17.5 from mast base to where
alum. meets the beginning of the pulley assembly. From the old RX1 trim
guide, seems this should be just about perfect. Problem is, I can't downhaul
it to the 18 cm mark, which is about 3 cm from the pulley. I'm > 1 cm.
short. More downhaul takes MASSIVE effort, even with a tool, and I'm still
nowhere near the max. I'm pretty sure my lines are run correctly, unless
something's totally changed.

I find I get a bit more downhaul if I downhaul partially, outhaul fully,
downhaul fully (or as best I can). This is my first race sail . . . is there
some secret sequence?

I'm pretty sure I'm under downhauled because my bottom batten won't rotate
like I think it should.

Do I lengthen my extension another 3 cm to get more leverage? Do I buckle
up, quit being a ***, and really haul the damn thing (way more than any
other sail I've had)? Do I need some crank tool? Am I measuring or doing
something else wrong? Is it possible to over downhaul and rage equipment to
bits?

Thanks,

Jeff

Jeff,

We demo a 7.8 RX2 with the 490 Race Pro Mast, 2000 Neil Pryde extension.  I
do Neil Pryde demos for Island Surf and Sail on the Jersey Shore.

The only way to correctly rig this sail is to downhaul it to within 1 cm of
the cleat with the exact extension length as published on the sail.  Using a
Chinook extension, you must mark off the correct extension length by
comparing the extension against a Neil Pryde or Fiberspar extension.  You
must then adjust the 1cm length to compensate for the Chinook extension.
Check out the new 2000 Neil Pryde carbon base, these are better than the
Chinook in my opinion, mainly because they allow you to downhaul more easily
than the Chinook.

If you still can't downhaul manually, time to get a mechanical downhaul tool
like the Rigmaster.  Besides, it will save your back!  Check out some tools

Jerry, Jerry, Jerry...
  The Mailhaul by Aboora rolls much better than the Rigmaster rocks.
